Thanks for the advise, I just google some pictures of the projector and found out it's a Sharp.

Am planning for a 120" screen fixed frame and would definitely check out the brand and models of the couch for you (if there's a label on it :p)

I think I would move the left over Marantz AVR to living room and also eagerly to find out if he had done any networking wiring at all (big hope! :p), because I don't think using wireless can reach the basement and for streaming of video, a wired connection would be better off.
